The eldest daughter of a peasant family: They are all my sisters’ passers-by

There was a flash of understanding in the girl's eyes. It turned out that she was curious about this.

"This is a prepared medicine powder. Just mix it with hot water. The ready-made medicine is not as effective as the medicine prescribed by a professional doctor, but it can be used in an emergency."

Her tone was calm and she gently pinched Lan Luochen's forearm with her hand.

"Luo Chen, get up and take your medicine."

Lan Luochen was in a daze and felt his forehead was a little heavy. Lan Wangshu took off the handkerchief, ran it over with cold water again, wiped his face and neck, and tested the temperature with his hand.

She fed him the medicine like porridge, and then stuffed two candy vitamins into his mouth.

"Go to sleep, you'll feel better after a good night's sleep."

The warm palm touched his face, and Lan Luochen felt that she was particularly gentle and endearing.

"elder sister."

Lan Wangshu smiled and nodded, saying softly.

"I'm here."

Only then did Lan Luochen close his eyes contentedly and fall asleep peacefully.

"You are a very good sister."

Mo Yici was the adopted son of General Zhennan. His father died on the battlefield and his mother followed him, entrusting him to General Zhennan. The general pitied and appreciated him, and adopted him as his son and raised him by his side.

The military environment is very harsh. I have to endure all my illnesses since childhood on my own and have never been taken care of like this before.

"Really? It's not easy for you to praise someone."

Lan Wangshu is not a person who holds grudges, especially against people who have no ill will towards him. His temporary unhappy emotions come and go quickly.

"I was the one who offended Miss Lan before, but I still have a question that I want to ask Miss Lan."

Lan Wangshu looked at Lan Luochen, who was sleeping quietly with his eyes closed and nodded, and the two of them tiptoed into the yard.

"If there's anything you want to know, just tell me."

"Why do you use wine to rub the palms of your hands and soles of your feet?"

"Because evaporation absorbs heat, alcohol dissipates heat faster than water."

"What is evaporation?"

Lan Wangshu was stunned for a moment, then turned his head to look at Mo Yici. No way, there is still someone who doesn’t know how to evaporate. The man was also looked at inexplicably, mainly because Lan Wangshu’s eyes were filled with the four words "you are ignorant".

He lowered his head and thought carefully, and indeed he had never heard of it.

Lan Wangshu pointed to the clothes hanging on the clothes rack, and then pointed to the sun in the sky.

"Do you know why we have to wash clothes early in the morning and leave them in the sun?"

“Because clothes dry quickly.”

"Yes, the sun is hot, and the water absorbs the heat and evaporates, turning from liquid to gas, and the clothes dry. Is that hard to understand?"

"It's not difficult."

Lan Wangyu had squatted beside her at some point and answered in a low voice.

Lan Wangshu was amused by him and hugged the man in his arms. The two of them, one big and one small, looked at Mo Yici with their similar faces. The man also nodded to show that he understood.

"Sister, Xiaoyan also wants to be hugged."

"Master will hold you."

Mo Yici looked at her small body and thought that she probably couldn't hold another person, so she reached out and held Lan Wangyan in her arms.

"How did Miss Blue find out?"

"This is the wisdom of life. With your status, you don't need to do these things yourself. I just didn't pay attention."

“Then why did you wash the handkerchief with water and put it on your forehead instead of using wine?”

"Because strong liquor is irritating, it will cause a burning sensation after drinking it. The skin on the face is so delicate, and if you keep applying it, it will hurt the skin."

"Thank you, young lady. I'm grateful for your advice."

"Easy to say."

Lan Wangshu always felt that he had forgotten something and sat in his chair in a daze.

"Boss, are you feeling uncomfortable somewhere?"

Zhou Xingnan leaned against the wall, holding a straight wooden stick with a very round cross-section in his hand. Looking at her somewhat conflicted expression, he couldn't help but ask.

"I always feel like I forgot to do something."

"Sister, sow seeds, wood."

Lan Wangyu raised his head from her arms and spoke in a low voice.

"Yes, thanks to Xiaoyu, otherwise I would have forgotten. Is Xiaoyu interested in this?"

She intended to guide Lan Wangyu to explore his scientific research talent, and of course would not miss this opportunity.

"kindness."

The little guy nodded vigorously, looking like he had been waiting for a long time.

When Zhao Boping raised the issue of low sowing efficiency, her first reaction was a picture of a plow cart in a history book. One person, one ox, and one cart could sow one hectare of land in a day. The three-legged plow cart was particularly prominent and was even referenced in the murals.

Put the seeds in the seed bucket, dig trenches with three legs, and tilt them at an angle that allows the seeds to slide into the seed holes. Walk forward and the soil will cover them.

Once the car passes, the operations of digging trenches, planting and covering can be completed at the same time, with three rows working together. It is impossible for the efficiency to be low. However, this structure still needs to be carefully considered.

When Lan Wangshu was drawing with the charcoal pencil in his hand, his brain was constantly constructing a three-dimensional image. This may be the brain unique to liberal arts students. He has a strong sense of geometry and immediately discovered a problem, which is the timing and quantity of sowing.

She drew very quickly. Although the structure was simple, it would take her a long time to study it if she had imagined it out of thin air. Fortunately, she had a vision of thousands of years.

Lan Wangshu wanted to hear if Lan Wangyu had any new ideas, so he took out the blueprint and called the little guy over.

"Xiao Yu, tell your sister how to use this plow."
